Application filed August 12,1925, Serial No. 49,804. Renewed December 1827.

This invention relates to side frames for railway car trucks, and more particularly to the strengthening of such side frames adjacent the ends thereof.

The principal object of my invention, generally considered, is the reinforcement of the compression and tension members of a cast side frame adjacent the junction of said members aswell as increasing the strength of the union between journal boxes and the corresponding ends of the frame.

An object of my invention is the improvement in the design of the tension member of cast side frames for railway car trucks and its union with integral journal boxes at the ends thereof by curving the web of said tension member, which is preferably channel shaped in cross section, downwardly to unite with the side wall of the adjacent journal box and flaring the flanges of said tension member to follow the diverted web portion and thereby increase the area of the side Walls of the frame adjacent the journal boxes, said side walls being reinforced and the connection between the tension member and corresponding journal box increased by triangular web portions extendingfrom below the beginning of the curved'portion of the tension member web to approximately the upper inner corner of the corresponding journal box.

Another object of my invention is the improvement in design of side frames for railway car trucks in which the compression and tension members are generally channel sha ed in cross section and an integra-l journal ox is provided at each end` of the frame, the web of the tension member preferably extending generally in the direction of the upper inner corner of the adjacent journal box, by curving the web downwardly` adjacent said journal box to meet the side wall thereof, extending the tension member flanges to follow the web portion, and reinforcing said flanges, the tension member, and the connection between it and the journal box'by w'eb or rib portions extending from below the beginning of the curved portion of the tension member web along the flanges thereof to approximately thel up er inner corner of said journalA box where 1t merges therewith.

A further object of my invention is the improvement in the design of the tension member in cast side frames for railway car trucks, said side frames having a tension A still further ob'ect of my invention is.

the provision of a si e frame for railway car trucks, said frame having compression and tension members generally channel sha ed in cross section, the flanges of 4each mem er extending towards'those of the other and merging therewith, the edges of said flan es defining the outer portion of an opening e- .tween said members, said edges being reinforced by beading therealong which is formed of maximum depth or strength for a portion adjacent the junction between said members, gradually decreased both ways therefrom to a minimum yand then continued along said members at a substantially uniform depth or strength.

Other objects and advantages of the invention relating to the particular arrangement and combination of parts will become apparent as the description proceeds.

Referring to the drawing illustrating my invention, the scope whereof is pointed out in the claims:

Figure 1 is a fragmentary side elevation yof one end' of a side frame for railway car trucks embodying my invention.

Figure A2 is a fragmentary lan view of the side frame as illustrated in ,igure 1.

Figure 3 is a cross sectional view on the line 3 3 of Figure 1 and looking in the direction pf the arrows. Referring to the drawing moreparticularly, like parts being designated bylike reference characters, there is illustrated one end of a side frame 1 for railwa car trucks, the remainder of said frame, eing of well known construction and not involving features of my present invention, not being illustrated.

In the embodiment shown, the frame comprises a compression member 2, a tension member 3, the ends of said members being integrally united at 4, as is usual in such conf struction, and preferably formed with a journal box 5 adjacent the junction between the l tain of the aforementioned details, which are not part of m invention except as will be hereinafter pointed out, may be of any well known or preferred form. 'l

The compression member 2 and tension member 3 preferably extend substantially the fulllength of the side frame, as will be understood, and at each end of said frame there is provided a journal box 5 preferably integral therewith. Said compression and tension members, in the present embodiment, are formed generally U-sha ed in cross-section with a main web portion and flange ortions 8 on opposite sides of the web portion, said iiange portions, in the embodiment shown, extending inwardly or towards each other and merging at the junctions between the compression and tension members to form flat side wall portions which are extended over and unite with the roofs 9 of the journal boxes.

; The free edges of the flange portions are preferably beaded, thickened or provided with a rib 10 which extends around the corner of the triangular opening 6 from the compression member 2 to the tension member 3.

According to my invention said rib isspecially constructed so as to increase the strength of the frame at critical portions thereof, that is, the rib 10 although for the greater portion of its length is generally uniform in height or strength, is tapered or increased in height or strength along the compression member 2 from a. point above the junction of the compression and tension member portions to approximately said junction which is, in the present instance, slightly above the level of the journal box roof 9. From there it is continued at maximum height or strength downwardly along the edges of the tension member flanges to a point, indicated by 11, somewhat below the level of the journal box roof. From the point 11 the depth or strength of the beading 10 around the triangular opening 6 is decreased gradually to a uniform minimum and continued around said triangular opening as such.

The point 11, where the beading 10 starts to` taper or decrease downwardly, is preferably slightly above where the web 7 of the tension member 3 curves downwardly from a st-raight line. It will be noted that the plane of the main portion ofl said web 7, if continued, would meet the journal box at approximately the upper inner corner thereof, but in order Locate? tension member -3 are flared to correspond with the downward bending or curving of the web 7, thereby forming relatively large fiat side walls adjacent each journal box. These side walls are preferably strengthened or reinforced and the union between the fra-me and journal boxes rigidiiied by triangular web or rib portions 14 extending from below the beginnin of the curved portion of the web 7 prefera ly in line with the straight portion of said web, and continued to the adjacent journalbox, preferably uniting therewith at approximately the upper inner corner, as illustra-ted. These Webs or flanges 14, asv will be apparent, not only increase the strength of the union between the journal boxes and frame, but form a valuable reinforcement to the tension member at a particularly critical port-ion thereof.

The tension member 3 instead of being formed with flanges 8 decreasing in width, or converging toward the plane of the straight part of the web, from their lower inner portions to their upper outerportions for approximately the full length thereof, is preferably so constructed that said flanges reach a minimum in width at approximately the point where the web portion 7 curves adjacent the point 11 and from said point are increased oth ways.

By virtue of the aforedescribed construction the strengthof the side frame is greatly improved because the reinforcing anges 14 and the increased portions of the beading 10 are applied at critical sections of the frame. The increasing of the width of the tension member flanges above the point where the web 7 diverges from its normally straight direction also results in improving the strength at the same critical portion of the frame. That is, it will be seen that the portion of the tension member adjacent its outer or upper ends, where it is liable to break in service, is increased or reinforced in three Ways; first, by the triangular web portions 14, second. by increasing the width of the flanges 8, and third, by increasing the height, width or strength of the beading 10 at this point. This increase in strength of the tension member not only affects that member itself but also the connection between the journal boxes'and the frame, as will be understood. The web 7 of the compression member 2 is preferably curved downllO Having thus described the invention, I claim:
